Abstract
An injection control device opens and closes a fuel injection valve by driving the fuel injection valve with a current to control fuel injection to an internal combustion engine. The injection control device includes: a booster circuit that boosts a battery voltage; a boosting control unit that performs boosting control on the booster circuit; and a charge control setting unit that sets charge permission or charge prohibition for the booster circuit to the boosting control unit.
Claims7
An injection control device configured to open and close a fuel injection valve by driving the fuel injection valve with a current to control fuel injection to an internal combustion engine, the injection control device comprising:
- a booster circuit configured to boost a battery voltage;
- a boosting control unit configured to perform boosting control on the booster circuit;
- and
- a charge control setting unit configured to set charge permission or charge prohibition for the booster circuit to the boosting control unit, wherein:
- the charge control setting unit is configured to set the charge permission or the charge prohibition for the booster circuit to the boosting control unit according to an injection type,
- the injection control device further comprises an injection type determination unit configured to determine the injection type, and
- the charge control setting unit sets the charge prohibition to the boosting control unit when the injection type determination unit determines that the injection type is a learning minute injection, the learning minute injection being an injection that does not contribute to the driving of the internal combustion engine.
